更に、本実施形態における机１は、例えばグループワークや隣の人とペアで学習する場合など、同種の他の机１と天板１０同士を横方向に隙間なく配置させた状態での横連結が可能な構造となっている。以下、机１の軽量化を図りつつ机１同士の横連結およびスタッキングを両立することの可能な構造について詳しく説明する。 Further, the desk 1 in the present embodiment is horizontally connected in a state where the top plate 10 and another desk 1 of the same type are arranged laterally without a gap, for example, in the case of group work or learning in pairs with a neighbor. It has a structure that allows. Hereinafter, a structure capable of achieving both horizontal connection and stacking of desks 1 while reducing the weight of the desks 1 will be described in detail.

机１は、図２および図８等に示すように、前側支持体２１の前横梁部２１３と後側支持体２２の後横梁部２２３は傾斜している。前側支持体２１の前横梁部２１３は、天板１０の前縁１０ａと平行に配置されているのに対して、後側支持体２２の後横梁部２２３は、天板１０の後縁１０ｂに対して傾斜しており、右後脚部２２１と接続される右側端の方が、左後脚部２２２と接続される左側端に比べて、相対的に天板１０の後縁１０ｂに近接している。その結果、図８に示すように、左右一対の後脚部同士である右後脚部２２１および左後脚部２２２が、天板１０の奥行方向に互いにずれた状態（変位した状態）で配置されており、左後脚部２２２に比べて右後脚部２２１の方が天板１０の後縁１０ｂに近接して配置されている。なお、本実施形態においては、右後脚部２２１および左後脚部２２２の中心同士の前後方向（天板１０の奥行方向）のずれ量を、右後脚部２２１および左後脚部２２２の直径寸法（より詳しくは、キャップ２５の外径）よりも若干大きな寸法に設定している。これにより、後述する机１の横連結時において、連結する一方の机の左後脚部２２２と他方の机の右後脚部２２１とが干渉することなく、横連結する机の天板１０同士を横方向に隙間なく並べて配置することができる（図１０を参照）。 As shown in FIGS. 2 and 8, the desk 1 has an inclined front cross beam portion 213 of the front support 21 and a rear cross beam portion 223 of the rear support 22. The front cross beam portion 213 of the front support 21 is arranged parallel to the front edge 10a of the top plate 10, whereas the rear cross beam portion 223 of the rear support 22 is located on the trailing edge 10b of the top plate 10. On the other hand, the right end connected to the right hind leg 221 is relatively closer to the trailing edge 10b of the top plate 10 than the left end connected to the left hind leg 222. ing. As a result, as shown in FIG. 8, the right hind leg portion 221 and the left hind leg portion 222, which are a pair of left and right hind legs, are arranged in a state of being displaced (displaced) from each other in the depth direction of the top plate 10. The right hind leg 221 is arranged closer to the trailing edge 10b of the top plate 10 than the left hind leg 222. In the present embodiment, the amount of deviation between the centers of the right hind leg portion 221 and the left hind leg portion 222 in the front-rear direction (depth direction of the top plate 10) is determined by the right hind leg portion 221 and the left hind leg portion 222. The size is set to be slightly larger than the diameter size (more specifically, the outer diameter of the cap 25). As a result, when the desks 1 are laterally connected, which will be described later, the left hind legs 222 of one desk to be connected and the right hind legs 221 of the other desk do not interfere with each other, and the top plates 10 of the desks to be horizontally connected are connected to each other. Can be arranged side by side without gaps in the horizontal direction (see FIG. 10).

次に、右脚補強連結材２３および左脚補強連結材２４について詳しく説明する。図２および図８等に示すように、右脚補強連結材２３および左脚補強連結材２４は平面視Ｓ字形状を有する金属製の細パイプである。右脚補強連結材２３は、右後脚部２２１から天板１０の右側縁１０ｃの内側に向かって斜めに伸びる後脚側接続領域２３１と、右前脚部２１１から天板１０の右側縁１０ｃの外側に向かって斜めに伸びる前脚側接続領域２３２と、後脚側接続領域２３１および前脚側接続領域２３２を接続する中間領域２３３によって形成されている。同様に、左脚補強連結材２４は、左後脚部２２２から天板１０の左側縁１
０ｄの内側に向かって斜めに伸びる後脚側接続領域２４１と、左前脚部２１２から天板１０の左側縁１０ｄの外側に向かって斜めに伸びる前脚側接続領域２４２と、後脚側接続領域２４１および前脚側接続領域２４２を接続する中間領域２４３によって形成されている。 Next, the right leg reinforcing connecting member 23 and the left leg reinforcing connecting member 24 will be described in detail. As shown in FIGS. 2 and 8, the right leg reinforcing connecting member 23 and the left leg reinforcing connecting member 24 are thin metal pipes having an S-shape in a plan view. The right leg reinforcing connecting member 23 has a rear leg side connecting region 231 extending diagonally from the right rear leg portion 221 toward the inside of the right edge 10c of the top plate 10, and the right front leg portion 211 to the right edge 10c of the top plate 10. It is formed by a front leg side connection region 232 extending diagonally toward the outside, and an intermediate region 233 connecting the rear leg side connection region 231 and the front leg side connection region 232. Similarly, the left leg reinforcing connecting member 24 has the left rear leg portion 222 to the left side edge 1 of the top plate 10.
The rear leg side connection area 241 extending diagonally toward the inside of 0d, the front leg side connection area 242 extending diagonally from the left front leg portion 212 toward the outside of the left edge 10d of the top plate 10, and the rear leg side connection area 241. It is formed by an intermediate region 243 connecting the front leg side connection region 242 and the front leg side connection region 242.

また、図８に示すように、右脚補強連結材２３における中間領域２３３は、天板１０の右側縁１０ｃに沿って平行に延設され、後脚側接続領域２３１および前脚側接続領域２３２は天板１０の右側縁１０ｃに対して傾斜している。また、左脚補強連結材２４における中間領域２４３は、天板１０の左側縁１０ｄに沿って平行に延設され、後脚側接続領域２４１および前脚側接続領域２４２は天板１０の左側縁１０ｄに対して傾斜している。更に、図３～図６等に示すように、本実施形態に係る机１は、右脚補強連結材２３および左脚補強連結材２４は、段違いとなるように互いに異なる高さに横架されている。具体的には、左脚補強連結材２４に比べて、右脚補強連結材２３の方が低い位置に配置されている。 Further, as shown in FIG. 8, the intermediate region 233 in the right leg reinforcing connecting member 23 extends in parallel along the right edge 10c of the top plate 10, and the rear leg side connecting region 231 and the front leg side connecting region 232 extend in parallel. It is inclined with respect to the right edge 10c of the top plate 10. Further, the intermediate region 243 in the left leg reinforcing connecting member 24 extends in parallel along the left edge 10d of the top plate 10, and the rear leg side connecting region 241 and the front leg side connecting region 242 are the left edge 10d of the top plate 10. Is tilted against. Further, as shown in FIGS. 3 to 6 and the like, in the desk 1 according to the present embodiment, the right leg reinforcing connecting member 23 and the left leg reinforcing connecting member 24 are laid horizontally at different heights so as to be different from each other. ing. Specifically, the right leg reinforcing connecting member 23 is arranged at a lower position than the left leg reinforcing connecting member 24.

なお、本実施形態における机１では、左後脚部２２２および右後脚部２２１が天板１０の奥行方向に相互にずれて配置されており、左後脚部２２２に比べて右後脚部２２１の方が天板１０の後縁１０ｂに近接している（図８を参照）。これに関連して、本実施形態では、右脚補強連結材２３および左脚補強連結材２４のうち、左後脚部２２２に比べて天板１０の後縁１０ｂに対して相対的に近い位置に配置されている右後脚部２２１と連結されている右脚補強連結材２３を、右後脚部２２１に比べて天板１０の後縁１０ｂに対して相対的に遠い位置に配置されている左後脚部２２２と連結されている左脚補強連結材２４よりも、相対的に低い位置に横架するようにしている。 In the desk 1 of the present embodiment, the left hind leg portion 222 and the right hind leg portion 221 are arranged so as to be offset from each other in the depth direction of the top plate 10, and the right hind leg portion is arranged as compared with the left hind leg portion 222. 221 is closer to the trailing edge 10b of the top plate 10 (see FIG. 8). In this regard, in the present embodiment, the positions of the right leg reinforcing connecting member 23 and the left leg reinforcing connecting member 24 are relatively closer to the trailing edge 10b of the top plate 10 than to the left rear leg portion 222. The right leg reinforcing connecting member 23 connected to the right hind leg portion 221 arranged in is arranged at a position relatively far from the trailing edge 10b of the top plate 10 as compared with the right hind leg portion 221. It is laid horizontally at a position relatively lower than the left leg reinforcing connecting member 24 connected to the left hind leg portion 222.

＜横連結＞
次に、机１同士の横連結について説明する。図９および図１０は、横連結した状態の机１，１を説明する図である。机１，１を横連結した状態の斜視図を図９に示し、平面図を図１０に示す。なお、図１０において、机１の天板１０の外形を鎖線で示し、天板１０の下方に位置する支持構造体２０を透視している。また、図１０において、網棚４０、フック部２７、および緩衝部材２８等の図示を省略している。また、図９および図１０において、個々の机１を区別するために一方を符号１Ａで示し、他方を符号１Ｂで示す。 <Horizontal connection>
Next, the horizontal connection between the desks 1 will be described. 9 and 10 are views for explaining the desks 1 and 1 in a horizontally connected state. A perspective view of the desks 1 and 1 in a state of being horizontally connected is shown in FIG. 9, and a plan view is shown in FIG. In FIG. 10, the outer shape of the top plate 10 of the desk 1 is shown by a chain line, and the support structure 20 located below the top plate 10 is seen through. Further, in FIG. 10, the net shelf 40, the hook portion 27, the cushioning member 28, and the like are not shown. Further, in FIGS. 9 and 10, one is indicated by reference numeral 1A and the other is indicated by reference numeral 1B in order to distinguish the individual desks 1.

図９および図１０に示す例では、机１Ａにおける左側に机１Ｂが連結されている。すなわち、机１Ａにおける天板１０の左側縁１０ｄと机１Ｂにおける天板１０の右側縁１０ｃが対向した状態で、机１Ａ，１Ｂが並んで配置されている。 In the example shown in FIGS. 9 and 10, the desk 1B is connected to the left side of the desk 1A. That is, the desks 1A and 1B are arranged side by side with the left side edge 10d of the top plate 10 in the desk 1A and the right side edge 10c of the top plate 10 in the desk 1B facing each other.

机１Ａ，１Ｂの横連結時においては、机１Ａの左後脚部２２２に、机１Ｂ（他の机）の右脚補強連結材２３の上方を跨がせる（図９および図１０を参照）。そして、机１Ｂの右脚補強連結材２３を跨がせた机１Ａの左後脚部２２２を、机１Ｂの右後脚部２２１の斜め前方に配置する。その際、机１Ａ，１Ｂにおいては、右脚補強連結材２３および左脚補強連結材２４が段違いに形成され、左脚補強連結材２４に比べて右脚補強連結材２３の方が低い（図３～図６、図９等を参照）。これにより、机１Ｂの右脚補強連結材２３を机１Ａの左後脚部２２２に跨がせた際に、机１Ａの左脚補強連結材２４と机１Ｂの右脚補強連結材２３が干渉（衝突）することを抑制することができる。そして、机１Ａの左脚補強連結材２４と机１Ｂの右脚補強連結材２３が干渉（衝突）することに起因して机１Ａの左後脚部２２２が床面から浮いてしまうことにより机１Ａが不安定となることを抑制できる。 When the desks 1A and 1B are horizontally connected, the left hind leg 222 of the desk 1A straddles the upper part of the right leg reinforcing connecting member 23 of the desk 1B (another desk) (see FIGS. 9 and 10). .. Then, the left hind leg portion 222 of the desk 1A over which the right leg reinforcing connecting member 23 of the desk 1B is straddled is arranged diagonally forward of the right hind leg portion 221 of the desk 1B. At that time, in the desks 1A and 1B, the right leg reinforcing connecting member 23 and the left leg reinforcing connecting member 24 are formed in a stepped manner, and the right leg reinforcing connecting member 23 is lower than the left leg reinforcing connecting member 24 (Fig.). 3 to 6 and 9). As a result, when the right leg reinforcing connecting member 23 of the desk 1B is straddled over the left hind leg portion 222 of the desk 1A, the left leg reinforcing connecting member 24 of the desk 1A and the right leg reinforcing connecting member 23 of the desk 1B interfere with each other. (Collision) can be suppressed. Then, the left hind leg portion 222 of the desk 1A floats from the floor surface due to the interference (collision) between the left leg reinforcing connecting member 24 of the desk 1A and the right leg reinforcing connecting member 23 of the desk 1B. It is possible to prevent 1A from becoming unstable.

なお、右脚補強連結材２３と左脚補強連結材２４の高低差（右脚補強連結材２３の上端と左脚補強連結材２４の下端の高さ方向の離間寸法）Ｄ４（図５を参照）については、少なくとも右脚補強連結材２３（左脚補強連結材２４）の厚さ（直径）に比べて大きくすることが好ましく、そのようにすることで机１Ａ，１Ｂの横連結時において机１Ａの左脚補
強連結材２４と机１Ｂの右脚補強連結材２３の干渉（衝突）を回避できる。但し、右脚補強連結材２３と左脚補強連結材２４の高低差（以下、「左右脚補強連結材高低差」という）Ｄ４が右脚補強連結材２３（左脚補強連結材２４）の厚さ（以下、「脚補強連結材厚さ」という）よりも僅かに大きいだけに留まると、机１Ａ，１Ｂの横連結時に机１Ａの左脚補強連結材２４と机１Ｂの右脚補強連結材２３のどちらが高いのかを使用者が直感的に（一見して）判断することが難しいとも考えられる。 The height difference between the right leg reinforcing connecting member 23 and the left leg reinforcing connecting member 24 (distance between the upper end of the right leg reinforcing connecting member 23 and the lower end of the left leg reinforcing connecting member 24 in the height direction) D4 (see FIG. 5). ) Is preferably at least larger than the thickness (diameter) of the right leg reinforcing connecting member 23 (left leg reinforcing connecting member 24), and by doing so, the desk is connected when the desks 1A and 1B are horizontally connected. Interference (collision) between the left leg reinforcing connecting member 24 of 1A and the right leg reinforcing connecting member 23 of the desk 1B can be avoided. However, the height difference between the right leg reinforcing connecting material 23 and the left leg reinforcing connecting material 24 (hereinafter referred to as "left and right leg reinforcing connecting material height difference") D4 is the thickness of the right leg reinforcing connecting material 23 (left leg reinforcing connecting material 24). If it stays only slightly larger than the above (hereinafter referred to as "leg reinforcement connecting material thickness"), the left leg reinforcing connecting material 24 of the desk 1A and the right leg reinforcing connecting material of the desk 1B are connected when the desks 1A and 1B are horizontally connected. It may be difficult for the user to intuitively (at first glance) determine which of 23 is higher.

一方、各脚補強連結材２３，２４は、右前脚部２１１（左前脚部２１２）および右後脚部２２１（左後脚部２２２）の下部同士を連結して強度および剛性を高めるための補強材であるため、脚部の強度、剛性を大きくする観点からは、脚部のより下端に近い部位同士を連結することが有効である。これに対して、左右脚補強連結材高低差Ｄ４を過度に大きく設定すると、特に右脚補強連結材２３より高い位置に配置される左脚補強連結材２４の位置が高くなり過ぎてしまう傾向がある。そうすると、左前脚部２１２および左後脚部２２２の下部を連結することが難しくなり、左前脚部２１２および左後脚部２２２の補強効果が低減される懸念がある。そこで、左右脚補強連結材高低差Ｄ４については、机１Ａ，１Ｂの横連結時に互いに交差すべき右脚補強連結材２３と左脚補強連結材２４の何れが高いかを直感的に（一見して）容易に判断でき、且つ、過度にその高低差が大きくならない程度（例えば、数センチ程度であってもよい）にすると好適である。すなわち、左右脚補強連結材高低差Ｄ４は、右脚補強連結材２３と左脚補強連結材２４の何れが高いかを直感的に（一見して）容易に判断できる範囲で、なるべく小さな寸法にすることが好ましい。これによって、机１の脚部の強度、剛性を確保しつつ、横連結する机同士のどちらの脚部に連結先の脚補強連結材を跨がせるべきかを使用者が直感的に（一見して）判断することができるため、机１同士の横連結のやり易さと、脚部の強度、剛性の確保のし易さの双方を両立することができる。 On the other hand, the leg reinforcing connecting members 23 and 24 are reinforced to connect the lower portions of the right front leg portion 211 (left front leg portion 212) and the right rear leg portion 221 (left rear leg portion 222) to increase the strength and rigidity. Since it is a material, it is effective to connect the parts closer to the lower end of the legs from the viewpoint of increasing the strength and rigidity of the legs. On the other hand, if the height difference D4 of the left and right leg reinforcing connecting members is set excessively large, the position of the left leg reinforcing connecting member 24 arranged at a position higher than that of the right leg reinforcing connecting member 23 tends to be too high. be. Then, it becomes difficult to connect the lower portions of the left front leg portion 212 and the left rear leg portion 222, and there is a concern that the reinforcing effect of the left front leg portion 212 and the left rear leg portion 222 is reduced. Therefore, regarding the height difference D4 of the left and right leg reinforcing connecting materials, it is intuitively (at first glance) which of the right leg reinforcing connecting material 23 and the left leg reinforcing connecting material 24 that should intersect each other when the desks 1A and 1B are horizontally connected is higher. It is preferable that the height difference can be easily determined and the height difference does not become excessively large (for example, it may be about several centimeters). That is, the height difference D4 of the left and right leg reinforcing connecting members should be as small as possible within a range where it can be intuitively (at first glance) easily determined which is higher, the right leg reinforcing connecting member 23 or the left leg reinforcing connecting member 24. It is preferable to do so. As a result, the user can intuitively (at first glance) decide which leg of the desks to be horizontally connected should straddle the leg reinforcing connecting material of the connection destination while ensuring the strength and rigidity of the legs of the desk 1. Since it is possible to make a judgment, it is possible to achieve both the ease of laterally connecting the desks 1 and the ease of ensuring the strength and rigidity of the legs.

また、机１Ａ，１Ｂを横連結した状態において、机１Ａの左脚補強連結材２４と机１Ｂの右脚補強連結材２３は互いに交差した状態となっており、机１Ａの左後脚部２２２が連結対象である机１Ｂの天板１０の下方に位置すると共に、机１Ｂの右後脚部２２１が机１Ａの天板１０の下方に位置している（図１０を参照）。本実施形態における机１Ａ，１Ｂにおいては、右後脚部２２１および左後脚部２２２が天板１０の奥行方向に互いにずれているため、図１０に示すように、横連結時に机１Ａの左後脚部２２２と机１Ｂの右後脚部２２１とが干渉することを抑制できる。よって、机１Ａ，１Ｂの天板１０同士を横方向に隙間なく密着させた状態で配置させることができる。また、机１Ａ，１Ｂを横連結した状態において、机１Ａの左後脚部２２２に机１Ｂ（他の机）の右脚補強連結材２３を跨がせて配置しているため、机１Ａ，１Ｂの天板１０同士を横方向に離反する方向に外力が不意に加わったとしても、机１Ｂの右脚補強連結材２３に机１Ａの左後脚部２２２が引掛り、掛り止められる。その結果、机１Ａ，１Ｂにおける天板１０同士が離反することを抑制できる。つまり、本実施形態における机１の脚補強連結材２３，２４は、脚部の補強部材としての機能の他、机１同士を横方向に連結する際の連結機能を発揮する。その結果、机１同士の横連結が不用意に解除されることを好適に抑制することが可能となる。 Further, in the state where the desks 1A and 1B are horizontally connected, the left leg reinforcing connecting member 24 of the desk 1A and the right leg reinforcing connecting member 23 of the desk 1B are in a state of intersecting each other, and the left rear leg portion 222 of the desk 1A. Is located below the top plate 10 of the desk 1B to be connected, and the right rear leg 221 of the desk 1B is located below the top plate 10 of the desk 1A (see FIG. 10). In the desks 1A and 1B in the present embodiment, the right hind leg portion 221 and the left hind leg portion 222 are displaced from each other in the depth direction of the top plate 10. Therefore, as shown in FIG. 10, the left side of the desk 1A is left when horizontally connected. It is possible to suppress the interference between the rear leg portion 222 and the right rear leg portion 221 of the desk 1B. Therefore, the top plates 10 of the desks 1A and 1B can be arranged in a state of being in close contact with each other in the lateral direction without any gap. Further, in a state where the desks 1A and 1B are horizontally connected, the desk 1A and the desk 1A are arranged so that the right leg reinforcing connecting material 23 of the desk 1B (another desk) is straddled on the left rear leg portion 222 of the desk 1A. Even if an external force is suddenly applied in the direction in which the top plates 10 of 1B are separated from each other in the lateral direction, the left rear leg portion 222 of the desk 1A is hooked on the right leg reinforcing connecting member 23 of the desk 1B and is stopped. As a result, it is possible to prevent the top plates 10 of the desks 1A and 1B from separating from each other. That is, the leg reinforcing connecting members 23 and 24 of the desk 1 in the present embodiment exhibit not only the function as the reinforcing member of the leg portion but also the connecting function when the desks 1 are connected to each other in the lateral direction. As a result, it is possible to preferably prevent the horizontal connection between the desks 1 from being inadvertently released.

また、本実施形態に係る机１によれば、右脚補強連結材２３および左脚補強連結材２４によって前後の脚部の下部同士を連結して補強しつつ、天板１０同士を横方向に隙間なく密着させた状態で机１同士の横連結を行うことができるため、各脚部（右前脚部２１１、左前脚部２１２、右後脚部２２１、および左後脚部２２２）を細くしても強度的な要求を満たすことができる。その結果、机１の軽量化を実現することが可能となる。 Further, according to the desk 1 according to the present embodiment, the top plates 10 are laterally connected to each other by connecting and reinforcing the lower portions of the front and rear legs by the right leg reinforcing connecting member 23 and the left leg reinforcing connecting member 24. Since the desks 1 can be horizontally connected to each other without any gaps, each leg (right front leg 211, left front leg 212, right rear leg 221 and left rear leg 222) is thinned. However, it can meet the strong demands. As a result, it is possible to reduce the weight of the desk 1.

また、本実施形態に係る机１は、単純な４本脚構造であり、脚部を特殊な形状に加工する必要がない。更に、机１の右脚補強連結材２３および左脚補強連結材２４は、１本の鉄パイプに対して平面的な折り曲げ加工を施すだけで得ることができ、３次元の折り曲げ加
工が不要であるから、机１の加工精度が悪化することを抑制することができる。 Further, the desk 1 according to the present embodiment has a simple four-legged structure, and it is not necessary to process the legs into a special shape. Further, the right leg reinforcing connecting member 23 and the left leg reinforcing connecting member 24 of the desk 1 can be obtained only by performing a flat bending process on one iron pipe, and a three-dimensional bending process is not required. Therefore, it is possible to prevent the processing accuracy of the desk 1 from deteriorating.

＜スタッキング＞
次に、非使用時に机１同士を上下方向に積み重ねるスタッキングについて説明する。図１１は、机１，１を上下にスタッキングした状態を示す図である。図１１においては、下方に位置する机を符号１Ｂで示し、机１Ｂの上方に積み重ねられている方の机を符号１Ａで示す。 <Stacking>
Next, stacking in which desks 1 are stacked in the vertical direction when not in use will be described. FIG. 11 is a diagram showing a state in which desks 1 and 1 are stacked up and down. In FIG. 11, the desk located below is indicated by reference numeral 1B, and the desk stacked above the desk 1B is indicated by reference numeral 1A.

図３に示したように、本実施形態における机１は、右後脚部２２１および左後脚部２２２の離間距離Ｄ１が天板１０の横幅寸法Ｄ２よりも大きな寸法に設定されている。そのため、天板１０の下方において、右後脚部２２１および左後脚部２２２の前方には、他（下方）の机１における天板１０を配置可能な大きさの空間が形成されている。これによれば、図１１に示すように、机１同士を上下方向にスタッキングすることができる。 As shown in FIG. 3, in the desk 1 in the present embodiment, the separation distance D1 between the right rear leg portion 221 and the left rear leg portion 222 is set to be larger than the lateral width dimension D2 of the top plate 10. Therefore, below the top plate 10, a space having a size capable of arranging the top plate 10 of the other (lower) desk 1 is formed in front of the right rear leg portion 221 and the left rear leg portion 222. According to this, as shown in FIG. 11, the desks 1 can be stacked vertically.

また、本実施形態における机１においては、右脚補強連結材２３および左脚補強連結材２４の平面形状をＳ字形状とすることで、机１のスタッキング時に右脚補強連結材２３および左脚補強連結材２４が各脚部と干渉（衝突）することを抑制することができる構造となっている。具体的には、右脚補強連結材２３は、前脚側接続領域２３２が右前脚部２１１から天板の右側縁１０ｃの外側に向かって斜めに延在しているため、スタッキング時に上下に積み重なる他の机１の右前脚部２１１と右脚補強連結材２３（前脚側接続領域２３２）が干渉（衝突）することを回避できる。また、左脚補強連結材２４は、前脚側接続領域２４２が左前脚部２１２から天板１０の左側縁１０ｄの外側に向かって斜めに延在しているため、スタッキング時に上下に積み重なる他の机１の左前脚部２１２と左脚補強連結材２４（前脚側接続領域２４２）が干渉（衝突）することを回避できる。 Further, in the desk 1 of the present embodiment, the plane shape of the right leg reinforcing connecting member 23 and the left leg reinforcing connecting member 24 is S-shaped, so that the right leg reinforcing connecting member 23 and the left leg are stacked when the desk 1 is stacked. The structure is such that the reinforcing connecting member 24 can be prevented from interfering (collising) with each leg. Specifically, the right leg reinforcing connecting member 23 is stacked up and down during stacking because the front leg side connecting region 232 extends diagonally from the right front leg portion 211 toward the outside of the right edge 10c of the top plate. It is possible to prevent the right front leg portion 211 of the desk 1 and the right leg reinforcing connecting member 23 (front leg side connecting region 232) from interfering with each other (collision). Further, in the left leg reinforcing connecting member 24, since the front leg side connecting region 242 extends diagonally from the left front leg portion 212 toward the outside of the left edge 10d of the top plate 10, other desks that are stacked up and down during stacking. It is possible to prevent the left front leg portion 212 of 1 and the left leg reinforcing connecting member 24 (front leg side connecting region 242) from interfering with each other (collision).
